Title:
DRIVING FORCE CONTROLLER FOR VEHICLE
Document Type and Number:
Japanese Patent JP2009035191
Kind Code:
A
Abstract:

To perform high-accuracy traction control by suppressing control delay to suppress an initial slip, in a driving force controller for a vehicle.

This driving force controller for the vehicle is provided with: an HV-ECU 20 controlling driving torque of an engine 12 and motors 16, 19; a brake ECU 40 controlling braking torque of a brake actuator 38; a rotation position detection sensor 35 detecting rotational speed of the motor 19; and a wheel speed sensor 47 detecting rotational speed of a driving wheel 28. The brake ECU 40 detects the slip based on the rotational speed of the driving wheel 28, calculates a first torque down amount, and outputs it to the HV-ECU 20. The HV-ECU 20 detects the slip of the driving wheel 28 based on the rotational speed of the motor 19, calculates a second torque down amount, and controls the driving torque of the motor 19 according to the first torque down amount and the second torque down amount.
